LDM (Layered Deployment Model): A Novel Framework to Deploy Sensors in an Irregular Terrain

引用

Wireless Sensor Network 2011年第6期3卷 189-197页

作者： Chandan kr. Bhattacharyya swapan Bhattacharya 不详

Deployment of sensors in any irregular terrain with 100% coverage and connectivity is a challenging issue in the field of Wireless Sensor Networks. Traditional deployments often assume homogeneous environments, which ignore the effect of terrain profile as well as the in-network obstacles situated randomly like buildings, trees, roads and so on. Proper deployment of sensors in such irregular region and its corresponding routing is one of the most fundamental challenges of Wireless Sensor Networks. In this work, we have considered that the terrain is irregular in shape and there may be obstacles within the terrain in any random position with any random shape, which is the reality in real world. With this novel framework, we have shown that an opti-mum deployment can be achieved in such irregular terrain without compromising coverage as well as con-nectivity between the sensor nodes for effective routing.

Ethnopharmacology, phytochemistry and pharmacology of Tephrosia purpurea

引用

Chinese Journal of Natural Medicines 2014年第1期12卷 1-7页

作者： Satadru Palbag Bijay kr.dey Narendra Kumar Singh Faculty of Ayurveda Institute of Medical Sciences Banaras Hindu University Bengal Institute of Pharmaceutical Sciences SPLPIM Campus Jadavpur University

Tephrosia purpurea(L.) Pers. is popularly known as ‘Sarapunkha' in classical Ayurvedic texts. It is a perennial plant belonging to the family Fabaceae, and occurs throughout the Indian subcontinent. T. purpurea is traditionally used to treat spleenomegaly, cirrhosis, cough and cold, abdominal swelling and as an antidote in the Ayurvedic system of medicine. Phytochemical investigations indicate the presence of semiglabrin, pongamole, lanceolatins A and B, rutin, lupeol, and β-sitosterol. Flavonoids including(+)-tephrorin A and B,(+)-tephrosone, an isoflavone, 7, 4'-dihydroxy-3', 5'-dimethoxyisoflavone and a chalcone,(+)-tephropurpurin were isolated from the whole plant. Pharmacological activities of different parts of the plant reported include anti-inflammatory, antiulcer, antimicrobial, antioxidant, antiallergic, antidiabetic, hepatoprotective, antitumor and insect repellent activity. In the present review, the literature on the phytochemical and pharmacological investigations of Tephrosia purpurea(L.) Pers. are summarized to August, 2012.

An Exploratory Study on Allelic Diversity for Five Genetic Loci Associated with Floral Organ Development in Rice

引用

American Journal of Plant Sciences 2015年第12期6卷 1973-1980页

作者： Alok Priya Soumya Prakash Das Sayani Goswami Malay kr. Adak Debal Deb Narottam dey Department of Biotechnology Visva-Bharati Santiniketan-731235 West Bengal India Plant Physiology and Plant Molecular Biology Research Unit Department of Botany University of Kalyani Kalyani-741235 West Bengal India Basudha Barrackpore Kolkata-700120 West Bengal India

Allelic diversity for five genetic loci (DL, FON4, OsMADS24, OsMADS45 and Spw1) associated with floral organ development were investigated among a small heterogeneous rice population which included one wild species (O. rufipogon Griffiths), one indigenous less popular natural floral organ mutant (O. sativa var. indica cv. Jugal), one indigenous normal line (O. sativa var. indica cv. Bhutmoori) and one improved high yielding line (O. sativa var. indica cv. IR 36). Detailed spikelet morphology showed that var. Jugal had variable number (1 - 3) of carpels within a single spikelet which was unique and resulted in variable (1 - 3) number of kernels within a single matured spikelet (grain). The genomic DNA of each investigated line was amplified with primer sequences designed from the selected genetic loci and the derived polymorphism profiles were used for study of allelic diversity for the studied loci. The derived genetic distances among the rice lines were used for dendrogram construction. In constructed dendrogram, the mutant genotype (Jugal) showed highest similarity with the wild rice (O. rufipogon) instead of the rice lines. To verify this finding, the genomic DNA of each studied line was also amplified with four SSR loci, tightly linked to saltol QTL, mapped to rice chromosome 1. The amplified products were screened for polymorphism and another dendrogram was constructed to reveal the genetic distance among the lines for selected salt tolerance linked SSR loci. In SSR derived dendrogram, the wild rice (O. rufipogon) got totally separated from the all three rice genotypes though all the studied four lines showed equal sensitivity for salt sensitivity in a physiological screening experiment. From the combined experiment, it can be concluded that genetic architecture of floral organ development loci in var. Jugal may have some uniqueness which is not present in normal rice but common to O. rufipogon, a species which is regarded as immediate progenitor of present day
